He was hired as the head coach of the Cleveland Browns in 2014, and was sacked after the 2015 season. Prior to that, however, Pettine was a successful defensive coordinator.

Pettine had a top-10 defense in each of his five seasons as a coordinator, including first (2009), third (2010), fifth (2011) and eighth-place (2012) rankings with the Jets and a 10th-place showing with the Bills in 2013. He hired Joe Philbin, the former coach, to rejoin his staff likely as offensive coordinator to replace Edgar Bennett, who will not return. After moving up through the ranks in Baltimore, Pettine spent four years as Rex Ryan's defensive coordinator with the Jets and one season under Ryan with the Bills. Additionally, Pettine was a coaching assistant with the Baltimore Ravens (2002-2003), as well as Baltimore's assistant defensive line coach (2004) and outside linebackers coach (2005-2008).

Green Bay coach Mike McCarthy announced last week the team would interview Packers assistants Winston Moss, Darren Perry and Joe Whitt for the job.
